At Booksy, I built an engineering-intelligence platform from scratch to replace manual Confluence governance, and automated Eppo stale-flag cleanup across the firm. I also shipped OpenAI API features in Eppo experiments and co-built an AI reviewer.

At Friendly-Event.com, I founded an MVP family and events platform and architected its Vue/Nuxt, Node.js, and PostgreSQL stack. Its production deployment achieved near-maximum Core Web Vitals, technical SEO, and TTFB.

At Lumilinks (Zaven) and on IKEA US's Teamo product, I led frontend and full-stack delivery, including team leadership and Vue migrations. Earlier, I worked on e-commerce and government map products, and delivered NLP dashboards and web applications at Wrocław University of Science and Technology · CLARIN-PL.
